Why have consumer startups fallen out of favor and why might that be the biggest opportunity of the next decade? In this episode, I talk with Brian O’Malley, founder of Tactile Ventures, about why consumer investing is deeply misunderstood and how AI is unlocking a new wave of products that improve everyday American lives. Brian shares lessons from two decades investing at Accel, Battery, and Forerunner, why incentives—not talent—drive venture outcomes, and how the best consumer companies blend technology, business models, and human behavior. We also explore why AI is moving out of its “toy phase,” why humans still need to stay in the loop, and how early-stage investors win by giving founders something large platforms can’t: time.

How do you raise $875M in one of the hardest fundraising markets in decades and still outperform on DPI, IRR, and culture? In this episode, I sit down with Jesse D. Serventi and Atif Gilani, Founding Partners of Renovus Capital Partners, to unpack what actually compounds in private equity over 15+ years. We break down why staying in the lower end of the lower middle market creates structural advantage, how talent density became their real edge, and why portfolio construction—not deal hype—is the hidden driver of net returns. Jesse and Atif also share how Renovus evolved from three founders doing everything into a scaled firm built to last decades, not cycles.

What separates enduring investment firms from those that quietly break as they scale? In this episode, I talk with Chris Brimsek, Managing Partner of CAB Advisory, about the unseen mechanics behind building durable alternative investment firms. Drawing from his experience as Chief of Staff to David Rubenstein and former COO of Carlyle’s $15B Infrastructure & Energy business, Chris explains why culture, judgment transfer, and succession—not deal mechanics—are the true bottlenecks to long-term performance. We unpack how elite leaders create environments without intellectual hierarchy, why forgiveness builds trust faster than perfection, and how emerging managers can avoid the most common traps as they scale.

How well do venture capital returns really reflect skill versus structure? In this episode, David Weisburd speaks with Abe about what large-scale AngelList data reveals about seed investing, power-law returns, and why traditional assumptions around expected value, conviction, and diversification often break down.
